It seems the images you pull out of Google are not georeferenced so the Data Inspector shows them all on top of eachother. If you have it group by layer_id for example you can see it's different tiles.

That would make it harder to overlay the parcel boundaries. You may want to try the Landsat or Sentinel on AWS readers instead (they do return a georeferenced image)

The parameters of the Inspector transformer. Mind you, that only groups them for the inspector.

Yes, that's what I said. The images are not georeferenced so FME can't display them in the proper geometric relation to eachother. Try the Landsat or Sentinel one instead (they're also free to use, which may not be the case with Google)

There's a tutorial here https://knowledge.safe.com/articles/43678/tutorial-reading-and-working-with-satellite-imager.html

 

 

Sentinel is probably the best one to work with, I haven't tried Landsat myself to be honest.

@redgeographics

 

Thanks for the information

 

I did tray the sentinel, but the resolution is an issue, compared to Google Map

 

Again thanks for you help
